IMPROVEMEN'l IN MACHINES FOR BURNISHING HEELS 0F BOOTS AND SHOES.

Specification forming part of Letters Patent No. 151,8I9, dat d June 9, 1.574; application filed December 3, 1873. f

To all whom it may concern is equalized, so that the same may press equally at all parts of the stroke, and upon all parts of the heel or other part that is to be burnished; second, in. improvements in the jacking device.

Figure 1 is an elevation of my machine. Fig. 2 shows an enlarged view of the burnisher and its heating device. Fig. 3 is an enlarged view of the upper part of the jack.

Upon any suitable standard like A I attach the head-block B, in which I hang the rocking shaft C. Motion may be communicated to this shaft C by any suitable means, it being necessary that the motion communicated be sufficient to 'throw the shaft through about two-thirds of a revolution-that is, enough to cause the burnisher D2, which is attached to it, as will be explained, to move entirely around the blacked edge of the heel. To the shaft C the head-block D is permanently at'- fixed, as shown in Fig. l. At the upper end of this head-block D I pivot the sha-nk D1 of the burnisher D2, so that the burnisher may be free to swing up and down. E is a bent lever, pivoted at d, on the lower end of the head-block B, Fig. 1. The upper end of this lever E is provided with a small roller, e, which rests upon the shank D'1 of the burnisher D2. S is a spring, operating on the lever E to force it down, and thus to depress the burnishingshank D1, and through it the burnisher D2. By arranging the bent lever E as described, and swinging on the pivot d,

. it will be seen that as the burnisher rises to do the higher part of its work the roller@ will run back on the lever D1, and thus lessen the ,leverage exerted by E on Vthe shank of the increases, this increase being compensated by the moving back of the point of contact at e, and thus lessening the leverage of the lever E. F, Figs. land 2, is a metallic hood. Gonnected with the burnisher D2, within this hood, I place a burner, F1, which serves to heat the burnisher. By adjusting the height of this burner the temperature of the burnisher can be regulated at will. The jacking device consists of a standard, H Hf, which swings on a pivot, h, in the arm K, Fig. l. This arm K furnishes a fixed support for the jack, and holds it in such a position that the heel of the shoe will be held at a proper point for the action of the burnisher for that part of the edge of the heel that is nearest the vamp where the heel is largest. As that part of the heel near the top lift, which is ot' smaller circumference, is brought under the burnisher, the radius of the arc of motion ot' the burnisher D2 is So much lessened that the stroke of the burnisher iS not long enough t0 reach the lower part of the edge of the heel. To obviate this diflculty I place the foot-lever L under the end of the jack H, as Shown in Fig. l. By placing the foot on this lever L the jack is thrown up, so as to bring the heel suciently high for the stroke of the burnisher to reach to the breast ofthe heel. Heretofore the jack has been set so that the stroke of the burnisher would extend low enough to reach the breast of the heel at the top lift. Then, when the large part. of the heel was being burnished, the burnisher stroke would reach below the breast of the heel and injure the edge of the sole of the shank. H2 H3 is a goose-neck, the upper end of which, H3, holds the boot or shoe. The lower end of this gooseneck is pivoted by m to the Swing-block M, Fig. 3, so that the goose-neck and shoe or boot may be swung on the vertical axis of m, so that the boot or shoe may be taken oit'. H5 is a clasp or shield, which projects over the shoe to prevent its being taken off except the goose-neck be first turned on the axis fm. The object of this is to cause the machine to be self-recording, as the recording device is located in m, and is loperated by the turning of the goose-neck, as above. The block M is pivoted by m1 to H, as shown in Figs. l and 3, so that the goose-neck H2 H3 can be thrown PATENT OFFICE.

up and forward by means of the eccentric M2, which is operated by the lever M3, Fig. 3. By throwing up M3 the goose-neck H3 is thrown forward, so as to press the boot or shoe hard lagainst the standard H1, and hold it iirm while being burnished.

I claim as my invention- 1. The combination of the lever E and spring S with the burnisher shank D1, operating` substantially as described, and for the purpose set forth.

2. The combination of the jack-support H, the arm K, and lever L, with the burnishing device D2, lever D, block D, and sha-ft C, all

operating substantially as descr bed, and for the purpose set forth.

8. The shield H5, in combination with the goose-neck H2 H3, substantially as described, and for the purpose set forth.

4. The combination of the block M and the cam M2 with the goose-neck H2 H3, substantially as described, and for the purpose set forth.
